Ahhh, the cruise. It’s the ultimate hands-off, let-someone-else-plan-your-trip getaway.

Sometimes it’s nice to leave the itinerary, the menu and the ports of call to someone else. Of course, kicking back comes a whole lot easier if you do some planning before you embark. This means determining whether you need to pack a passport for your cruise.

You may have heard mixed input, with some folks saying that cruises are great because you don’t need to pack a passport. Others may recall their own cruise disaster where a passport was a must — and they didn’t have one. So, what’s the deal? How do you know when you need to pack your passport for a cruise and when you can leave it at home?

If you’re short on time, here’s the quick answer: You should bring your passport whenever you’re leaving the country, just to be safe. You also should protect yourself with travel insurance, which can help you if you lose your passport or other travel documents.

But, if you’re looking for specifics (maybe you forgot to renew your passport, don’t have one, or are halfway to your cruise port already and accidentally left your passport at home), read on.

Which Cruises Don’t Require a Passport?

Not all cruises have the same passport requirements. If you’ve heard about an international cruise where a passport isn’t required, that’s most likely a “closed-loop” cruise. A closed-loop cruise is one that starts and finishes at the same U.S. port and only sails to Canada, Mexico, the Caribbean or the Bahamas.¹

For these cruises, you do not need a passport for re-entry into the United States. American citizens do, however, need:

• Proof of citizenship, such as an Enhanced Driver's License (EDL), a government-issued birth certificate, a passport card, or a passport.
• Proof of identification, such as a driver's license or official picture ID.

Keep in mind that, while you may not need a passport to embark on a closed-loop cruise and return home, you might need it to enter certain countries along the way. It’s best to check the specific entry requirements for each foreign port you’ll be visiting before leaving your passport at home.

Children may need just a birth certificate or other proof of citizenship, but not a passport or photo ID. Double-check your cruise line’s ID requirements, because there’s no room for error. One couple had planned a closed-loop cruise from Baltimore, and they mistakenly believed they only needed their driver’s licenses to board. Because they didn’t have their birth certificates or other proof of citizenship, they weren’t permitted to board — and they weren’t eligible for a refund.²

Where Else Can I Cruise Without a Passport?

There are a few U.S. territories and other destinations that allow passport-free entry for U.S. citizens.

• Puerto Rico is a United States Commonwealth, and all U.S. citizens can travel there and to its surrounding islands, Vieques and Culebra, without a passport.
• Also in the Caribbean, the U.S. Virgin Islands are a U.S. territory that’s fair game for passport-less American citizens. You can visit St. Croix, St. Thomas and St. John — just not the neighboring British Virgin Islands.
• In the Pacific, some cruises visit Guam, where, “although U.S. citizens are required to possess a U.S. passport, on a case-by-case basis, photo I.D. and proof of citizenship may be accepted.”³
• Cruises to Alaska and Hawaii don’t require passports, because both are U.S. states. However, if your Alaskan cruise begins or ends in Canada, you’d need your passport.

Take note: Just because you don’t need a passport to visit these destinations doesn’t mean you won’t need any official documentation. Make sure you have a government-issued photo ID, naturalization paperwork, and/or birth certificate.

Which Cruises Do Require a Passport?

If a cruise begins at one port and ends in another port, even if they’re both in the United States, passengers are required to have a valid passport. Similarly, if a cruise starts or finishes in a foreign port, travelers must come prepared with a current passport.

Certain Caribbean nations require cruise passengers to have a valid passport in order to enter: Barbados, Guadeloupe, Haiti, Martinique, St. Barts, St. Martin, and Trinidad & Tobago.⁴ If you don’t have a passport, you still can sail on a cruise that calls on these islands — you’ll just have to stay on the ship while it’s in port.

Of course, a valid passport is required for any cruise touring Europe, traveling across the Atlantic Ocean, or originating in another country. You won’t even make it onto the plane that will get you there without a valid passport.

Can I Go on a Cruise With a Real ID?

A Real ID is an upgraded, more secure driver’s license that’s required for domestic flights as of May 7, 2025. (A passport or Enhanced Driver’s License can also be used for identification on domestic flights).

A Real ID is not equivalent to a passport, however. Nor is it the same thing as an Enhanced Driver’s License (EDL), which is a special license, available to residents of a few states, that proves citizenship. Even if you have a Real ID, you’ll still need to bring a birth certificate or other proof of citizenship for a closed-loop cruise.

What If I Unexpectedly Need My Passport While on a Cruise?

It happens more often than you think! Let’s say you’ve booked a closed-loop cruise in the Caribbean, so you leave your passport at home. Then, an emergency occurs. For instance:

• You miss your embarkation and you need to fly to Cozumel to meet the ship. But you can’t do that without a passport; air travel to Mexico requires a passport, and no other form of ID is accepted.⁵
• During the cruise, your ship experiences a mechanical failure that requires it to dock in the Dominican Republic. You may be able to disembark in D.R., but you can’t fly home and re-enter the U.S.
• While on board, you suffer a heart attack and require a medical evacuation to a hospital on St. Lucia. The doctor recommends you return to the United States for treatment — but you don’t have a passport for the flight home.

If you have travel insurance, then Allianz Global Assistance can help you apply for the needed travel documents and make new travel arrangements. Depending on the benefits included, your plan may reimburse medical bills for a covered medical emergency while traveling and/or pay for a medically necessary evacuation following a covered medical emergency (see your plan for details).

The best rule of thumb, according to the U.S. Department of State: “Always bring your passport in case of an emergency, such as an unexpected medical air evacuation or the ship docking at an alternate port in an emergency, even if your cruise says you won’t need it.”⁶

What If I Lose My Passport While on a Cruise?

When you’re traveling, anything can happen. Your passport could do a swan dive off the deck of your cruise ship, or it could fall out of your pocket while you’re exploring a port of call. What happens then?

You’re going to need to replace it, fast. In situations like this, Allianz Global Assistance customers should call 24-Hour Hotline Assistance, or use the free Allyz® TravelSmart app for instant hotline access. Our Assistance experts can help expedite the process of replacing your lost passport and/or getting temporary travel documents issued.

If your travel insurance plan includes trip interruption benefits, then you may also file a claim for reimbursement if you miss at least 50 percent of the length of your trip due to lost or stolen travel documents.

What happens if you don’t have travel insurance? Unfortunately, you’re on your own. You’ll have to contact the nearest U.S. embassy or consulate to request a new passport. The cruise line can’t help you, and most likely will not give you any financial compensation. So don’t delay: find a travel insurance plan now.

The Final Word on Bringing a Passport for Your Next Cruise

As a rule of thumb, you should plan to take your current U.S. passport (with a date that is good for at least six months past the end of your trip) when you’re packing for a cruise. If you are traveling to U.S. territories or are taking a closed-loop cruise, your cruise line may not require a passport. However, you’ll need to show proof of citizenship and identification, and a passport is the simplest way to do both.

Our final advice? Book your cruise and purchase travel insurance at the same time. Cruising should be all about peace of mind, and the extra security that travel insurance provides is icing on the cruise-shaped cake. Plus, it helps you to feel comfortable booking your cruise far in advance, which can help get you better rates and deals. Both steps could save you some major anxiety and travel headaches; and relaxing is what a cruise is all about!
